Accessibility Solutions for Visually Impaired Persons

Abstract

This chapter aims to address a study in which it is intended to conceptualize, develop, and evaluate an aggregation platform of accessible solutions target to Portuguese people with visual impairment, incorporating not only an information layer but also a training layer using, for example, explanatory videos and tutorials. The platform contents will be nourished through a logic of volunteering and be available through an interactive television (iTV) application and a web/mobile application accessible to visually impaired users. In this chapter, a state-of-the-art survey is made to identify types of digital solutions target to visually impaired users. Based on this survey, an analysis is made to understand what features and functionalities the proposed platform can integrate and how it can become a powerful solution for people with visual impairment. In addition to the state-of-the-art survey and its analysis, the chapter includes the identification and description of the system architecture that will support the proposed platform.
